theme function does not return anything in custom module

Hi,
I am trying to upgrade my 4.7 custom module to 5.1.
Based on the instructions in the Handbook I have changed my code under hook_view in order to show my custom fields.
The problem is, that when I use a code as suggested in the Handbook:
$node->content['my_field'] = array(
'#value' => theme('mymodule_my_field', $node->additional_field),
'#weight' => 10,
);then nothing is displayed in the node preview. But when I just skip the theme function, like that:
$node->content['my_field'] = array(
'#value' => $node->additional_field,
'#weight' => 10,
);then I am able to see my data. The problem is independent of the theme used in the site...
I just don't get it, what I am doing wrong...
Hi milosh, you probably
Hi milosh,
you probably haven't got a function
<?phptheme_mymodule_my_field($additional_field){
return $additional_field;
}
?>
This is used so that you or other people can easily overwrite the default theme of that field with a mymodule_my_field.tpl.php file... That way they can theme the field without modifying your module code.
So just add that function in your module and it should work. :-)
